Yes I stand corrected, with unsigned ints and optimisations turned on the time for C++ for multiplication drops from 3.13 to 0.39 thats an almost 10 times speed up , with doubles and max optimisation on its 0.9
Yes I am using Pharo 32 bit. I think so, unless vmLatest now downloads Pharo 64 bit. So the conclusion is that C++ without the max optimisation on is almost as fast as Pharo. Still 10 times diffirence is not bad at all , on the other hand CPython3 on my iMac needs 118 seconds to finish the multiplication and for some strange reason the python 2.7 included with macos just hangs there forever. So Cpython at for me appears around 30-20 times slower... which is kinda weird too. But then Cpython has no JIT VM.
